FREDERICK E. STANLEY, OF WATEBBUBY, CONNECTICUT, ASSIGNOR TO SCOVILL MANUFACTURING COMPANY, OF WATERBURY, CONNECTICUT, A CORPORATION OF CONNECTICUT.

BIVETING-MACHINE.

To all whom it may concern. V

Be it known that I, FREDERICK E. STAN- LEY, a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented a certain new and useful Improvement in Riveting-Machines, of which the following is a full, clear, and exact description.

The immediate object of this invention is .io to provide a machine for accurately and readily setting rivets and burs on garments, and other articles where needed, "and where andwhen it is desirable to present a neatand symmetrical appearance of the riveted or upset end of the rivet; but the invention in principle is applicable to riveting or setting machines generally.

he invention consists of a riveting machine having a raceway intercepted by a setting plunger so that the bur or female member will be definitely delivered to the holder in setting position, and a stationary anvil or die onto which the rivet or male member is delivered andby which it is presented to 2b the setting plunger in a releasable way, and a reciprocating fingerfor moving the male member from its point of delivery to the anvil, as I will proceed now to explain and finally claim. so In the accompanying drawings illustrating the invention, 1n. the several figures of which like parts are similarly deslgnated, Figure 1 is a side elevation of the machine with the parts in position when the bur is about to' be delivered to the holder, the stand or post being broken out between its foot and upper end. Fi 2 is a front elevas tion of the upper part 0 the machine. Fig.

3 is a fragmentary sectional elevation of the plunger, holder and die with female and male members in position ready to be set. Fig. 4 is a front elevation, on a arger scale, of the anvil members. Fig. 5 is a erspective view of one of the yielding chee -pieces or jaws of the anvil, looking at its inner side. Fig. 6 is a sectional elevation of the upper part of the machine showing its extremes of movement by full and dotted lines, respectively. Fig. 7 is a perspective view so of the anvil members shown in Fig. 4, with the cheek-piece or jaw in the foreground detached. Fig. 8 shows in top plan and cross-section the female member or bur. Fig. 9 shows in inverted plan and artial longitudinal section the male mem er or Specification of Letters Patent.

rivet, in the instance shown, a tack. Fig.

10 shows the male and female members set or riveted upon two thicknesses of material. Fig. 11 shows the obverse of the joint of the push-finger, on a larger scale. so

As already stated, the invention in principle is applicable for riveting generally for setting buttons by means of metallic fastenings, such as tacks or rivets, and for other purposes, but the invention will be better 5 understood by explaining it as embodied in a machine for setting rivets and burs such as illustrated in Figs. 8 to 10 of the accompanying drawings, and this I will proceed now to do, with the understanding that the invention is not limited to the particular use or machine shown.

A stand or post 1 supports a table 2 on which rises a suitable head 3 to take certain moving and other parts of the machine.

4 is a bracket in which the main shaft 5 is mounted, and 6 is a band pulley thereon by which power may be applied. Any suitable stopping and starting mechanism ma be used for effecting the cooperation o the pulley and shaft, it being here noted that an intermittent rotary motion is used for operating the setting elements of the machine when the rivets are to be set at irregular intervals or at such points as require careful adjustment of the article to be riveted in order to secure the proper location of the rivets, as on the pockets, flies and other parts of overalls. The treadle 7 may be connected by rod 8 with the crank arm 9 of the stopping and starting mechanism, so as to put it in control of the operator.

The head 3 has a bracket 10 which supports the bur hopper 11, and another bracket 12 which supports the tack or rivet hopper '95 13,. and these hoppers are provided with chutes or raceways 14 and 15, respectively, which lead to the setting plunger 16 and the anvil 17 respectively.

The plunger, 16 is arranged vertically in the head and is jointed to a lever 18 pivoted at 19 on the head and connected by a connecting rod 20 with a crank-arm 21, or other suitable means on the shaft 5. This connectingrod may be and preferably is of the shock-absorbing type illustrated in my Patent No. 1,134,973, dated April 6, 1915.

The plunger 16 has its die end 22 made with a cavity 23 shaped to receive the socket portion 24 of the bur 25 and to center the bur over the tack 26, and this cavity also has a teat 27 to enter the depression 28 in the .burs socket, so that in the setting or riveting of the article the bur is held by the die end of the plunger both on its flange and its socket and its deformation prevented in the act of setting or riveting, and the tack point meets a solid resistance member which compels its upsetting or clenching within the socket of the bur. Furthermore, the contour of the depressed socket simulates the riveting where no protecting cap is used, but in a symmetrical and pleasing or attractive finish. The burs are delivered edgewise one at a time from the raceway 14 to the plunger while the plunger is in the setting position, and are arrested by the plunger until the plunger has returned and then a bur is dropped into the bur-holder in position to be acted upon by the plunger upon its next descent or setting movement." This bur-holder is composed of a pair of laterally-separable fingers 29 pivotally connected at 30, and havin their adjacent sides recessed to conjointly 50TH] a slot 31 in which are screws 32 backed 'by washers 33 which screws are threaded into the face of the head so as to secure the holder to the head in a longitudinally sliding relation and yet permit of the lateral separation of the fingers to discharge the bur. The fingers are held closed by any suitable resilient means, such as a spring 34 fastened to the fingers near their pivotal points, as by clips 35, and having their opposite ends bent into holes in the outer edges of the fingers near their lower ends. The holder is hung to the pivot 36, Fig. 1, which connects the lever 18 with the plunger 16, by means of hooks 37 so as to insure a positive return or upward movement of the holder. The tips 38 of the fingers extend backwardly beneath and in line with the plunger, and these tips are recessed at 39, Figs. 3 and 6, to receive the bur, flange down, and locate it directly beneath the plunger with its cap or socket in line with the die cavity in the end of the plunger, so that as the plunger descends to set or rivet the article, the bur socket will enter the die cavity in the plunger and the holder will be carried down with the descending plunger partly by gravity and partly by the contact of the plunger, and finally reaching its limit of movement determined by the engagement of the upper end of the slot 31 with the uppermost screw 32, the plunger in its further descent will part or separate the constituent fingers laterally and carry the bur down with it to the tack or rivet.

The anvil 17 comprises a block 40 mounted upon the table and having converging sides 41 at its front and a raceway 42 at its rear into which opens the tack raceway or chute 15 transversely. The anvil has a seat 43 of a shape correspondin to the shape of the head of the tack or rivet. To the inclined sides are yieldingly fitted the cheek-pieces or jaws 44, normally projected above the level of the anvil as by springs 45, and capable of moving downwardly. These cheekpieces are secured to the anvil not onl in such way as to permit this downward yielding movement, but also to have a laterally yielding movement, and these two movements may be obtained by the use of the slots 46, screws 47 and springs 48, in addition to the springs 45. The cheek-pieces ield downwardly under pressure of the plunger so as to permit the bur and tack or rivet to meet in close contact on opposite sides of the article being riveted, and to ultimatel release the tack head from the cheek-pieces, and they yield laterally to insure a spring engagement of the tack head and release it when set. The inside of each cheekiece is provided with a horizontally arrange tapering groove 49 alined with the raceway 42 and running out to nothing forward, so as to hold the tac or rivet by its head until set. The downward movement of the cheek-pieces and their lateral yield insure the release of the tack-head from these grooves when the riveting is completed. The springs 45 may be of wire, held to the anvil by screws 50, one of their ends resting on the base of the anvil and their other ends engaging pins 51 on the cheek-pieces.

The raceway 42 and the cheek-pieces combine to guide the tack or rivet from the hop per raceway to the point of a plication, and the tack or rivet is positive y moved into position by a push-finger 52, having its for ward end 53 flat and inclined upward and real-wardly and its ti beveled and crossing the raceway. Said nger slides back and forth over the raceway from just behind the hopper raceway 15 to a point forwardsufficient ly far to insure the location of the tack dr rivet in the seat 43, where it is held by the cheek-pieces closing in yieldingly upon it until the plunger descends in the act of setting or riveting as previously described. his push-finger is yieldingly ivoted at its rear end to an arm 54whic is pivotally suspended from a pin 55 mounted in a bracket 56 fixed to the head 3, and this arm is held up by a spring 57 stretched between it and the head so as normally to throw the push-finger forward while the yielding connection of the push-fin er with said arm tends to hold the forwar end of the push-finger in contact with the anvil. This yielding connection may be a coiled or other spring 58 mounted upon the pin join- 'ing the push-finger and arm and having its opposite ends engaging the push-finger and arm,'as shown in Fig. 11. The arm is engaged by a pin or roller 59 on one limb of a bell-crank lever 60 also pivoted on the pin 55, the other limb of this bell-crank lever engaging a slot in a link 61 hung from the lever 18, so that the push-finger is auto matically retracted as the lever 18 is raised to depress the plunger, and a loose motion is provided to ermit the push finger to move forward und r the combined action of the descending lever 18 and the spring 57.

The raceway 42 is provided with a cam surface 62 rising above its level from a point in advance of the raceway 15 where it enters the raceway 42 and extending to the rear of it. The cam surface serves to lift the pusli finger over the raceway 15 where it joints raceway 42 and permits its inclined leading end to ride safelyover the point without jamming the tack or rivet in the raceway and to enga e such point in its forward movement su ciently to move the tack or rivet beyond the cam surface and then drop 'behind it and push it into position on the anvil and into engagement with the spring cheek-pieces by which it is held to be set. There is enough play in the raceway 42 for the head ofthe tack or rivet to permit the latter to tilt un er the receding push-finger.

The bur hopper 1 1 is here shown as 'ven an intermittent rotary motion to fee the burs to the raceway 14, by a pawl and ratchet mechanism 63 actuated by a rod 64 connected with a awl carrier 65 at one end I 1 operation 0 push-finger a ain moves forward and places and a bell-crank ever 66 at the other end;

. the'pawl carrier bein "mounted on the hopper shaft and the be l-crank lever pivoted on the bracket 10 and having a forked end 67 engaging a pin 68 on the lever 18. The

pawl carrier is also connected by the rod 69 with the cut-off or gate 70 on' the raceway 14 and operates it to discharge one bur at a time. The tack or rivet hopper 13 is given an intermittent rotary motion, by means of a pawl and ratchet mechanism 71 having a pawl carrier 7 2 loose on the shaft of the ho per and connected by rod 73 with the be 1- crank lever 60. This pawl carrier has a rod 74 which is connected with the cut-oil or gate 75 on the tack or rivet raceway 15 to operate it to release the tacks or rivets one at a time.

The operation is as follows: Assuming that the machine is to be used. for riveting or setting rivets or tacks and burs of the character illustrated in Figs. 8, 9 and 10, wherein the bur instead of being of annular ,form as-usual, has a cap or socket made with or applied to it, so as to receive and conceal the upset or clenched or riveted end of the fastening, and such fastening is a tack, and

that these devices are to be used for staying the meeting edges of parts of garments. such as the pockets, flies, and other parts of overalls, then such burs are placed 1n the hopper ,11 and fed to the raceway 14 by the intermittent rotation of the hopper and from the raceway delivered one by one by its cut-ofi' or gate 7 0 to the plunger 16 and then the holder. Tacks are placed in the hopper 13 "a setting plunger, means to de they arei positioned beneath the plunger and bur by the cooperation of the push-finger 52 and the cheek-pieces 44. The arment to be riveted is held between the ur-holder and cheek-pieces, and then the plunger descends and carries the bur with it and out of the holder, depressing the cheek-pieces and forcing the tack through the garment into the bur and clenching it within the cap or socket of the bur, the bur meanwhile being supported within and b the die end of the plunger, and the finishe riveting presenting a smooth, symmetrical appearance, simulatin more or less closely, the best machine rivetmg. Should the bur fall into the holder askew, as indicated in Fi 3, it will be righted by the plunger. The push-finger moves a tack into settin position and remains in this position while the plunger and holder are descending and until the tack is about toenter or. has entered the garment, and thus its fiat forward end may be utilized as a support for the garment during the first part of the settin operation. Just before the riveting is e ected, the push-finger recedes, the fplunger and holder complete the riveting and then rise, and the another tack in position for another riveting operation. As shown in Figs. 2 and 6 the head is arched at its bottom and through this arch the push-finger plays. Any suitable means may be used to limit the forward movement of the push-finger, such as the rear wall of the arch, as indicated in Fig. 6.
